The 2 speed does decrease the load on the motor at lower speeds and from a stop decreasing temps somewhat. You also have the advantage of a pretty low Kv and higher voltage improving efficiency and lowering temps also.
If it were me, I'd try it as a single speed with your motor and go from there. Try gearing it for about 40mph or with a pinion that has the same tooth count as first gear. You might have to add a heatsink/fan but that's pretty common for those motors. Some more detailed info on your current setup and future plans will help. Motor Kv, current esc and future, current gearing 1st and 2nd, tire size, etc.

the current gearing is whatever the stock LST2 comes with. The tires currently are cen chevron tires, 7.5 inch I believe. Current ESC is an airplane ESC 100amp that came from bp hobbies, they don't seem to sell it anymore, the 60amp they sell is basically the same thing. I think thats part of the problem for me as I don't think the airplane esc has the throttle response I need. It works but its nowhere near as smooth as my sons new mini summit brushless. The motor kv I believe is 1500KV or somewhere around there.
I would like to go with a hobbywing ezrun 150amp esc or the turnigy 150amp although probably the hobbywing as it seems to have a much better rep and its only like 12 bucks more.
That opens up the option of going single speed and forward only which i'd like to do as I much prefer the motor braking.
One big question is I see pretty much all the motors are 2000KV and higher and that seems what everyone is running. Can I run that type of KV on 6s? I'd prefer to be able to buy a simple 40 dollar brushless motor and replace it if needed. Don't have the bucks for the expensive stuff. When I did the conversion years back, I was told you needed lower KV , but I seem to be reading a number of places that people are using these higher KV motors on 6S.
EDIT: one other thing, are there other motor mounts for this truck besides TDR, Losi and Fine Design? Just wondering because I see a number of motors with heatsinks built into the casing and pretty sure those aren't fitting in the losi mount and definately won't fit the FD mount which leaves the TDR mount which IMHO looks like the best option, but its also quite pricey.
